GitHub's RSA SSH private key was accidentally leaked to the public, as confirmed by the code hosting platform's CEO, Mike Hanley. 

"This week, we discovered that GitHub.com's RSA SSH private key was briefly exposed in a public GitHub repository," he announced via his official blog post. 

Hanley, who is also GitHub's SVP of Engineering, said that they quickly contained the exposure and investigated the root cause of the issue. 

GitHub's RSA SSH Private Key Accidentally Leaked to Public!

Instead, the RSA SSH host key was exposed to the public because of a plain, old human error. 

Because of this simple accident, the Github.com RSA SSH private key was leaked into a public GitHub repository. 

Although this might seem alarming, Hanley clarified that the private key leak doesn't affect the web traffic to GitHub.com and HTTPS Git operations. 

He added that it doesn't grant access to their customer data or infrastructure. 

However, the RSA SSH host key exposure can still affect developers since it can cause connection errors and send warning messages. 

Thankfully, GitHub was able to fix the problem on Mar. 24.

What GitHub Users Should Do 

Mike Hanley said that GitHub users relying on GitHub's ECDSA or Ed25519 keys don't have to worry about anything. 

But, if you receive the warning message "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!," then developers need to remove the old private key they are using. 

The GitHub CEO said that developers can remove their old key by running the command "$ ssh-keygen -R github.com."
